Ewen McKenzie remains confident that his Wallabies team has the ability to unleash his preferred brand of razzle-dazzle rugby, but he concedes after the humbling defeat by South Africa in Brisbane that his forwards must set a platform before swinging the ball wide.

McKenzie considered "dumbing down" his tactics following last week's 38-12 hammering at Suncorp Stadium, saying "either we're playing a game that is too complicated or the skill level doesn't match it" after the Wallabies' bid to unleash their backs backfired due a host of unforced errors and a lack of fight at the breakdown.

"Rugby's a highly technical game and it's got lots of moving parts," McKenzie said ahead of The Rugby Championship Test against Argentina in Perth on Saturday.

"You can play 1000 different ways. Our mission is to play with the ball in hand and challenge the opposition and play with skill. None of that's changed. Our philosophy hasn't changed at all. There are little areas of the game where we can tweak things. We've made some minor adjustments.

"If you change big things, you actually don't know what makes the biggest influence. So with small changes - which is what we've been doing for the last few weeks - we'll get there."

Brumbies forwards coach Laurie Fisher, meanwhile, believes the Wallabies players are not receiving clear communication about expectations and the game plan.

Dumbing down poor choice of phrase, Wallabies just need a bit more structure and clarity around roles. Less decisions, better communication.
